Includes specialized cord for 4-stage charging control of two 12V or 24V DLS chargers operating in parallel.

The IQ4 Smart Controller provides intelligent automatic charging control for your DLS Battery Charger, keeping batteries fully charged and operating for long life. IQ4 Charge Controllers are available for any DLS Battery Charger model and are backed by IOTA's Two-Year Warranty. The IQ4 Charge Controller allows the DLS Series battery charger to operate as an automatic 4-Stage "Smart Charger," delivering the charge your battery needs at the time it needs it. The IQ4 uses four different charging modes to keep your battery in peak condition. Bulk Stage: The Bulk Stage of the IQ4 allows the batteries to be charged from the full rated output of the charger (for example: a 12V charger will charge at a maximum of 14.8V*). This increased charging period reduces the overall charge time of the battery. Absorption Stage: After the Bulk Stage, the IQ4 then moves to the Absorption Stage (14.2V for a 12V battery*). This mode will continue for up to 480 minutes (8 hours) to ensure that the battery receives a complete charge. Float Stage: During the Float Stage, the IQ4 reduces the DLS charge voltage. This reduced voltage maintains the full charge while minimizing ‘gassing’ of the battery. The IQ4’s Float Stage prevents boiling and bulging of the battery caused when the battery is exposed to higher charging voltages for too long. Equalization Stage: If the batteries remain in a “float stage” for a seven-day period, the IQ4 will switch the DLS charger into a pre-programmed Equalization Stage. This protects the battery by dissolving any sulfate layer on the battery’s internal plates and avoids stratification that can occur when a battery has not been used for extended periods.
